Answer:
Step-by-step explanation:
an equation is : Use the point-slope formula.
y - y_1 = m(x - x_1) ; m : the slope when : x_1 = -3 and y_1 = 7
- 2 ×m = - 1 because this line is perpendicular to the line y= -2x-5 when the slope is -2
so : m= 1/2
an equation is : y - 7 =(1/2)(x+3)
400,246 ( 200,200-77=200,123 divide by .5= 400,246
Answer:
The area of a label is ![62.8\ in^{2}](https://tex.z-dn.net/?f=62.8%5C%20in%5E%7B2%7D)
Step-by-step explanation:
we know that
The lateral area of a cylinder (label of the can) is equal to
![LA=2\pi rh](https://tex.z-dn.net/?f=LA%3D2%5Cpi%20rh)
we have that
A can is 4 inches wide
so
The diameter of the can is 4 inches
----> the radius is half the diameter
----> height of the label
substitute in the formula
![LA=2(3.14)(2)(5)=62.8\ in^{2}](https://tex.z-dn.net/?f=LA%3D2%283.14%29%282%29%285%29%3D62.8%5C%20in%5E%7B2%7D)
The standard form of a line: Ax + By = C where A, B and C are integers.
Answer:
2x + 3y = -6
-4x + 3y = 12
x - y = 5
